Patent GB-2441927-A (GB)
Title: Active controlled bottomhole pressure system and method with continuous circulation system
Inventor: KRUEGER SVEN
IPC: E21B19/16
Filed: 2006-06-16
Abstract: An APD Device provides a pressure differential in a wellbore to control dynamic pressure loss while drilling fluid is continuously circulated in the wellbore. A continuous circulation system circulates fluid both during drilling of the wellbore and when the drilling is stopped. Operating the APD Device allows wellbore pressure control during continuous circulation without substantially changing density of the fluid. The APD Device can maintain wellbore pressure below the combined pressure caused by weight of the fluid and pressure losses created due to circulation of the fluid in the wellbore, maintain the wellbore at or near a balanced pressure condition, maintain the wellbore at an underbalanced condition, reduce the swab effect in the wellbore, and/or reduce the surge effect in the wellbore. A flow restriction device that creates a backpressure in the wellbore annulus provides surface control of wellbore pressure.

Title: Device for rotating the leg of a mole plough
Inventor: EVANS PAUL STUART
IPC: A01B13/08
Filed: 2009-07-13
Abstract: A device for rotating the leg 1 of a mole plough comprises a rotating flange 2, pivotable about pivot bolt 4. The pivot bolt 4 is positively attached to a fixed flange 6 which is in turn attached to the main beam 7 of a machine. Rotation of the flange 2 is achieved by a pair of hydraulic cylinders 8 acting in opposite directions about the pivot bolt 4. The leg 1 of the mole plough is thereby rotated from a vertical position to a horizontal position a plane of movement whereby the leg 1 of the machine remains at an angle of 900to the direction of travel of machine when in use, or to the main beam 7 of the machine. This has the effect of significantly reducing the working height of the machine when the leg is folded into the horizontal position.
